I'm not a biologist or any sort of doctor so this is just sort of a hot take stab in the dark. But here's my go. It's all about oxygen. If it's harder to breathe, less oxygen is getting to your brain, and that's never good. While it may not be life-threatening or anything, it might make you more irritable. Just constantly slightly fatigued and cranky. It takes less to set you off.
